I was doing a crossword from the NY Times (from Mon, Feb 11, 2019 by Portia Lundie / Will Shortz) and I got the following clue.
51 ACROSS - Times before eves, in ads
The answer is "AFTS". However, I do not understand why and how "AFTS" fits the clue.
Why is the answer "AFTS" and how does the clue fit?
